NON DESTRUCTIVE TESTING
Phased Array Ultrasonic Testing (PAUT)
• No radiation safety hazard issues
• Ensures continuous work, unlike RT wherein work area requires isolation of workers.
• Better detection of planar defects (such as cracks, lack of fusion, and lack of penetration)
• Complete details on the dimensions, i.e., length, depth, and height of weld imperfection, whereas RT can only produce the length of weld imperfection.
• Vertical sizing capability
• Real-time displays
• Great flexibility in parameter range
• Compliant with known codes
